BOTTLE-CLOSURE.

Specification of Letters Patent.

T0 at whom it may concern.-

Be it known that I; HENRY ALBERT OLssoN, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedBottle-Closure, of which the following is a full, clear, and exactdescription.

The principal object of my invention is to provide means for eifectuallyclosing the tops of bottles and other receptacles, and while it iscapable of general use it is especially adapted for use on milk-bottles.Many schemes have been tried for closing receptacles of this kind insuch a manner as to prevent the contents from being spilled and also toprevent foreign matter from entering them. One of the great troubleswith milk-bottles is that they are placed in ice-boxes with ice andother bottles above them, so that a fragile cover is likely to be brokenor bent, and the sediment from the ice necessarily settles in a pool onthe top of the closure when the ordinary paper disks are employed.Practically all of the other closures which have been adopted for thispurpose are expensive, and they also have faults which render them ofvery little more value than the paper disks.

My invention comprises means for efl'ectually closing bottles of thischaracter and also for protecting the interior of the bottle from theentrance of dirt and the like, the whole device being formed in such amanner as to render it inexpensive and easily constructed and employed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical sectional View of the top of a milk-bottle,showing a closure comprising the features of my invention. Fig. 2 is abottom plan view of the closure shown in Fig. 1; and Fig. 3 is a similarview to Fig. 2,

sion I place a disk 5, similar to the old style, but provided viith acovering-sheet 0, having a larger diame er than that of the disk 5 andextending abo ve the top edge of the bottle,

so as to prevent the entrance of foreign matters between it and the topof the bottle. These two disks or sheets are separated from each otherby means of a third disk (Z, which is smaller in diameter than either ofthe others, so that the disk 6 projects beyond the disk (Z all aroundand affords resilient flanges which hold the closure in the bottle-neck.The construction described provides an air-space e between the disks 6and c and between the disk (Z and the neck of the bottle. This air-spaceis effectually closed when the closure is applied to the bottle andassists in holding the article in place by suction. As the milk expandsupon being kept in the receptacle, this air-space also affords means forreceiving the surplus and prevents it from lifting the closure.

From the description given it will be clear that the lower disk I)accomplishes every pur pose which the ordinary single disk canaccomplish, and in addition thereto the top disk or sheet 0 effectuallyprotects the bottle as described, and also that the air-space 6 has theimportant function mentioned above. The device can be readily put inposition without any additionaltrouble, and it can also be removed whendesired by placing a knife under the edge of the sheet 0 and, ifnecessary, engaging the end of the knife with the disk d. If this is notsufficient, the closure maybe supplied with a strip f of cloth or thelike across the bottom of the disk 7) and projecting at the sides forconvenience in detaching it from the bottle.

The two disks 6 and 0 are preferably made of paraffin paper, while thecentral disk may be made of one or several shectsof strawboard, or itmay be formed by a block of wood. The three parts may be securedtogether in any desired way-as, for instance, by shellac.

In the form shown in Fig. 3 the disk (Z is replaced by a block d, havinga different shape, but afl ordingair-spaces of a larger size.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A bottle-closure comprising two parallel disks, andmeans for holding them at a distance from each other, the disks beingseparated from each other at their edges, whereby a marginal air-spaceis afforded when the closure is in position in a receptacle.

2. A bottle-closure comprising two parallel disks of differentdiameters, and means for holding them at a distance from each other andafiording an air-space between them, said means comprising a disk of thesame shape as the first-mentioned disks but of smaller diameter.

3. A bottle-closure comprising a disk adapted to enter the mouth of abottle, and a sheet secured to the disk at a distance from the latterand adapted to cover the mouth of the bottle.

4. A bottle-closure comprising a disk adapted to enter the mouth of abottle, a sheet secured to the disk at a distance from the latter andadapted to cover the mouth of the bottle, and a third disk between thefirst two and of a smaller diameter than either.

5. A closure for open-mouthed receptacles,

comprising a sheet adapted to project over 7 tom of the lower disk andadapted to project above the upper disk.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing Witnesses.
